Improved lubricating apparatus



UNITED STATES PATENT OEEIGE;

WILLIAM HAMILTON, OF CHIOOPEE, MASSACHUSETTS.

IMPROVED LUBRICATING APPARATUS.

Specification forming part of Letters Patent o, 58,409, dated October 2, 1866.

To all whom it may concern:

Be it known that I, WILLIAM HAMILTON, of Ghicopee, Hampden county, Commonwealth of Massachusetts, have invented a new and useful Method of Oiling Shafts; and I do hereby declare that the following is a full and exact description thereof,reference being had to the accompanying drawings, and to the letters of reference marked thereon.

In the drawings, Figure lis a section across the shaft and through my invention, and Fig. 2 is .a partial section through the bearings of the shaft and my invention.

In construction I form my apparatus of a cup having separate divisions within it, and attached under the bearings of the shaft in such a manner that a band or chain around the shaft hangs down into it, the oil being carried up from the cup and around the shaft by its adhesion to the chain, which is revolved by the motion of the shaft. The bearings of the shaft are constructed to suit this device.

In the drawings, A is .the cup, having separate apartments a b and the upper cup, c. B is the chain or band, and C the shaft, working in the bearings D and E. The cup A is attached to the tube F, into which thev chain works, and by it is attached to the hanger G in a suitable manner.

The upper cup, c, is arranged so as to only connect with the interior of the cup A by means of the little tube d. This tube is made just long enough to reach under the surface of the water, which is putin the lower apartment, b. On top of the Water, and principally occupying the apartment a, is placed the oil, lwhich is sustained by the superior specific gravity of the water.

In operation,.when the shaft is revolved, the chain or band hung over it, .and reaching down into the oil within the cup, is revolved with the shaft, and small particles of oil 'adhering to it are carried up around the shaft and work into the bearings'. Y The outside cup, c, is for the purpose of catching the drippings that fall mixed with dirt from the bearings. This oil, being caught in the cup c, runs down in the tube d, and when sufcient quantity is collected to give it enough weight it presses through the tube and rises above the surface of the water, mingling .with the oil through which the chain is passing.

The division g in the interior of the cup A, having an orifice in the middle under the chain, is for the purpose of confining the drippin gs that pass through the tube l as long as possible under the water, thus cleansing them thoroughly from dirt and rendering them iit to be used again. v

By this continuous economy a great deal of oil is saved that would be otherwise wasted, making avast difference inthe expense of running machinery.

Now, having described my invention, what I claim as new, and desire to secure by Letters Patent, is-

An oil-cup divided into separate compartments, as described, when said cup is combined with a chain or ring, B, by means of which the oil is carried up to lubricate the axle or shaft, in the manner and for the purpose herein described.

WILLIAM HAMILTON.
